SCCM 1606 Step by Step Upgrade Guide

SCCM 1606 Step by Step Upgrade Guide This post is basically a SCCM 1606 step by step upgrade guide. In my previous post we read that an update 1606 for System Center Configuration Manager was available. So basically 1606 for System Center Configuration Manager is an update that is available as an in-console for previously installed sites that run version 1511 or 1602. Yes the minimum SCCM version that you need to have is 1511 or 1602. If you are running SCCM 2012 R2 then you could upgrade to SCCM 1511. If you are looking to upgrade SCCM 1511 to SCCM 1602, click on this link. For more details and to view the full list of new features in this update check out our What’s new in version 1606 of System Center Configuration Manager documentation on TechNet.

How will i get SCCM 1606 Update ?

The new update should be automatically downloaded and you will be notified when it is ready to install from the “Updates and Servicing” node in your Configuration Manager console. If you can’t wait to try these new features, this PowerShell script can be used to ensure that you are in the first wave of customers getting the update. By running this script on your central administration site or standalone primary site, you will see the update available in your console right away. A small note from where to begin the upgrade, if you’re running a multi-tier hierarchy, start at the top-level site in the hierarchy (first CAS and then primary sites). After the top-level site upgrades, you can begin the upgrade of each child site.

Before you install this update it is recommended that you go through the upgrade check list provided on Technet. Also backup your site before you begin the upgrade.

In this post we will see the steps to upgrade SCCM 1602 to SCCM 1606. You can also upgrade to SCCM 1606 if you are running SCCM 1511.

When you right click on the update node you see two options –

a) Install Update Pack – Choose this option to install the update pack. Run this step once you complete the “Run Prerequisite Check” step.

b) Run prerequisite check – Run this check to make sure your configuration manager has all the prerequisites required before upgrade. If the prerequisite check step is successful, you will see the change in state of Prereq Only from No to Yes. It is highly recommended that you run the prerequisite check before the upgrade.

Right click on the update and click Run prerequisite check.

In the below step you have an option to upgrade the Configuration Manager without validating. If you choose this step it will overwrite your ConfigMgr client package with new version from the update. The second option is to validate in pre-production collection. This is basically to test the upgrade on a test collection first and then deploy it to production if everything is good. I am choosing the first option here, click Next.
